Air Quality Analysis

Ameren has achieved dramatic decreases in sulfur dioxide (SO2) emissions during the past two decades, despite a significant increase in the amount of electricity generated to meet our customers’ growing energy needs. Our philosophy is to stay ahead of regulatory mandates.

In response to recent U.S. Environmental Protection Agency (EPA) modifications of air quality standards, Ameren is proactively working with the Missouri Department of Natural Resources and other state officials to ensure accurate assessment of ground-level air quality around our Missouri generation facilities.

Setting the Record StraightMissourians enjoy good air quality. Because this issue is of vital importance to many, Ameren has commissioned an independent engineering analysis to refute misleading reports issued by environmental groups that oppose the use of coal as an energy source.
